I often travel east from Northfields at that time of day (well, any
time between 5:30 and 9:30), and it's not at all unusual to end up
on the outside (District) platform). I would estimate it happens to
me more often than once a fortnight.

There's a crossover from the EB fast to the EB local just west of
Acton Town. In 7 years, I think I've only been routed over it about 3
times. I note that EB 261 and 315 (ex Northfields at 2101 and 2142
respectively) are booked to do this move although I've never seen it
so it may be an Acton turn that does it.

You could, of course have travelled east along the EB local/test track
from Northfields.

I was travelling from the Rayner's Lane branch, which often uses
platform 4 at Acton Town. I hadn't realised that the Northfields branch
also sometimes used this platform, either from the fast or the local
lines. It was also the only time I've ever noticed two WB Piccadilly
line trains at Acton Town, with both getting green signals. The obvious
penny didn't drop till after we'd departed the station and stayed on the
local line.
